Snow Cover, Ice Volume Growth Show Global Climate Is A Lot More Than Just “Surface Temperature”

by P.  Gosselin, March 30, 2018 in NoTricksZone


Although a number of scientists are hollering that 2017 was “among the warmest on record”, we are not seeing any manifestation of this, at least over the northern hemisphere, where ironically snow and ice have shown surprising extents. This year the northern hemisphere winter has been surprisingly cold and brutal over a number of regions.

On March 20, 2018, northern hemisphere snow and ice cover was over 1 standard deviation above normal. Source: Environment Canada.

 

An “Exceptionally large amount of winter snow in Northern Hemisphere this year

by A. Watts, March 14, 2018 in WUWT


From the Snowfalls are now just a thing of the past department and the Finnish Meteorological Institute comes this press release today.

Exceptionally large amount of winter snow in Northern Hemisphere this year

The new Arctic Now product developed by the Finnish Meteorological Institute shows with one picture the extent of the area in the Northern Hemisphere currently covered by ice and snow. This kind of information, which shows the accurate state of the Arctic, becomes increasingly important due to climate change. The Arctic region will be discussed at the Arctic Meteorological Week which begins in Levi next week.

The Long Winter Of 2017/18…Numerous Records Set As Ferocious Cold And Snow Batter Northern Hemisphere

by P. Gosselin, February 20, 2018 in NoTricksZone


The long term forecast for Europe, where it is already colder than normal, shows temperatures plummeting to near -20°C in parts of Central Europe by early next week, extending what has been already a brutal winter.

Europeans longing for spring will just have to be patient for awhile. Indeed this winter has been a harsh one across the northern hemisphere with record cold temperatures being set from Siberia to North America to Japan. Also a number of places have seen record snowfalls.

The European Alps have had one of the snowiest winters in years as snow continues to pile up meters high.

Long list of harsh winter events (…)

Again And Again: Experts And New Findings Show No Link Between European Storm Activity And CO2

This month two major North Sea storms have hit Europe rather severely, and not surprisingly the usual climate ambulance chasers were out in force to try to pin the blame on man’s activity, and in doing so ignored the climate history that provides us with the proper perspective. We look at some analyses of past German storm activity.

COLLAPSE OF THE EUROPEAN ICE SHEET CAUSED CHAOS

by Maja Sojtaric, June 27, 2017


The Eurasian ice sheet was an enormous conveyor of ice that covered most of northern Europe some 23,000 years ago. Its extent was such that one could have skied 4,500 km continuously across it – from the far southwestern isles in Britain to Franz Josef Land in the Siberian Arctic. Suffice to say its existence had a massive and extremely hostile impact on Europe at the time.

This ice sheet alone lowered global sea-level by over 20 meters. As it melted and collapsed, it caused severe flooding across the continent, led to dramatic sea-level rise, and diverted mega-rivers that raged on the continent. A new model, investigating the retreat of this ice sheet and its many impacts has just been published in Quaternary Science Reviews.

Lowest Solar Activity In 200 Years Accompanied By High Northern Hemispheric Snow And Ice

by P. Gosselin from F. Bosse and F. Vahrenholt, June 18, 2017


In May the sun was very quiet as sunspot number was a mere 18.8, which is only 36% of what is typical for the month this far into the cycle. Seven days saw no sunspot activity at all.

The following chart shows the current cycle, Solar Cycle 24 (red), compared to the mean of the previous cycles (blue) and the similarly behaving SC 5 (black).

It’s clear that the current cycle is significantly weaker than the mean and far weaker than the cycles we saw throughout most of the warming 20th century.

New Paper: Northern Hemisphere Temperatures Rose 4–5°C Within ‘A Few Decades’ 14,700 Years Ago

By Kenneth Richard , April 2017


According to a new paper, the Bølling Warming event 14,700 years ago raised the surface temperature for the entire Northern Hemisphere by 4 to 5°C within a few decades.  This is a hemispheric warming rate of approximately 2.0°C per decade, which is 40 times faster than the 0.05 °C per decade global warming rate since 1850 (and 1998).

Atlantique Nord : le risque d’un refroidissement rapide au XXIe siècle revu à la hausse

par D. Swingedouw et al., CNRS, 15 février 2017


Dans le cadre du projet européen EMBRACE, une équipe d’océanographes a réexaminé ces 40 projections climatiques en se focalisant sur un point névralgique au nord-ouest de l’Atlantique Nord : la mer du Labrador. Cette mer est le siège d’un phénomène de convection, qui nourrit à plus grande échelle la circulation océanique de retournement. Ses eaux de surface se refroidissent fortement en hiver, deviennent plus denses que les eaux de profondeur et plongent vers le fond. La chaleur des eaux profondes est transférée vers la surface et empêche la formation de banquise
